25 de feb. de 2021 · The oxidation current increase at a potential of approximately 0.6V vs Ag/AgCl, is attributed to oxygen evolution. For higher potentials the current density follows the Tafel equation (see ...
9 de oct. de 2020 · Spectroelectrochemisty experiments carried out by setting alternatively the potential of the working platinum electrode at 0.9 V vs Ag/AgCl (Fc-to-Fc + oxidation) and at 0.1 V vs Ag/AgCl (Fc +-to-Fc reduction) induced enhancement/decrease of fluorescence emission for several cycles, with complete recovery of the intensity, demonstrating the ...
19 de feb. de 2022 · Of the three materials, Li 2 RuO 3 induced an anodic leakage current at the lowest onset potential, which is greater than 1.0 V versus Ag/AgCl (4.14 V vs Li/Li +); the anodic leakage current exceeds 20 mA g-1 presumably owing to continuous electrolyte oxidation.
However, in comparison with the reduction wave observed in nitrate and perchlorate solutions, both voltammetric signals here are shifted to a higher overpotential by ca. 0.1 V and most interestingly split into separated peaks at −0.4 V and −0.6 V vs. Ag/AgCl([Cl −] = 3.5 M).
18 de oct. de 2022 · Electrochemical impedance spectroscopy (EIS) was measured at 0.5 V vs. Ag/AgCl with a frequency range from 105 to 0.01 Hz.
The positive correlation between the onset of oxygen evolution in V vs Ag/AgCl (as derived from cyclic voltammograms determined at j = 200 µA cm⁻²) and the first momentum of the OH stretch...
Ag|AgCl E 0.6 V, SFC-ICP-MS analysis shows fast dissolution, and the oxide layer thickness is constant or increases. CA experiments during the OER show strong dissolution, and the re-formation of a
